Why a glass of cold water perspires with water drop when exposed to air?
Condensation of water vapour in the atmosphere into water droplets on the surface. The surrounding air contains water vapour. When the air touches the glass it becomes cooler and can no longer contain so much water, so it condenses out onto the glass.
Solid condensation on a surface that is below 0C is known as?
Water vapour changing to solid on a surface is sublimation of the vapour. For water the product is referred to as rime or hoarfrost.
What happens with water vapor when its cooled?
when water vapour is cooled it condenses and falls as rain
What happens to the energy used to evaporate water?
It goes into the molecules of water vapour, which are more energetic than those of liquid water
What happens when water vapour cools down below 100 degrees?
melts
What is the chemical or physical explanation for why water explodes when tossed on a grease fire?
Because as soon as water touches the hot surface, the bottom part, where the water touches, changes to vapour instantly! this happens so fast, that when it expands, it expands with explosive force and even pushes the water on top of the vapour outwards. this may carry some oil with it.
Why there is water on glass when ice melts?
because the water vapour in the air touches a cold surface such as glass and then turns back into water on the cold surface and this process is called condensation
How the water changes froim gas to liquid?
Water vapour (commonly referred to as steam) is turned back into liquid by a process of condensation. When the warm vapour touches a cold surface (a window pane, for instance) the vapour cools and forms droplets of liquid water.
What happens to water vapour when it evaporates from the earth's surface?
When water vapor is evaporation outside it rises to the sky and goes through the water cycle.
Why a glass of cold water perspires with water drop when exposed to air?
Condensation of water vapour in the atmosphere into water droplets on the surface. The surrounding air contains water vapour. When the air touches the glass it becomes cooler and can no longer contain so much water, so it condenses out onto the glass.
What happens when you breathe on a window and water droplets appear?
The water vapour in your warm breath condenses back into water on contact with the cold surface of the window.
How the water vapour condenses on the mirror?
The surface of the mirror is cooler than the surroundings. When the water vapour comes into contact with the surface of the mirror, they condense.
How Do Water Droplets Form?
water droplets form when a cold surface touches a hotter surrounding air and condenses to form water droplets
Solid condensation on a surface that is below 0C is known as?
Water vapour changing to solid on a surface is sublimation of the vapour. For water the product is referred to as rime or hoarfrost.
What happens to water it evaporates?
it becomes water vapour in the air
What happens to steam before it becomes water vapour?
Steam is water vapour - just a very hot form of it.
How do you change water vapour into water?
Water Vapour is removed from the kitchen by a ventilation system that is often installed over the stove which leads through the vents to the outside wall of the house, propelling the substance into the environment.
